INFLUENCE OF QUANTITATIVE ALLOYING OF TOOL STEELS FOR HOT DEFORMATION ON THE LEVEL OF HARDENING by V. N. Fedulov

“…The influence of complexly experimental tool steels: C (0,4–0,50%), Si (0,6–1,2%), Mn (0,17–0,8%), Cr (0,8–3%), W (0,9– 4%), Mo (0,01–3.5%) and V (0,28–1,8%) on their ability to hardening due to only high-temperature tempering after induction melting, casting in the ceramic mold and air cooling (without deformation) and after the various modes of complete heat treatment cycle…”

Fractal Loading Model of the Joint Interface Considering Strain Hardening of Materials by Yanhui Wang, Xueliang Zhang, Shuhua Wen, Yonghui Chen

“…Based on fractal geometry theory, the deformation state of the four stages of the asperity elastic, first elastoplastic, second elastoplastic, and fully plastic deformation and comprehensively considering the hardness of the asperity changes with the amount of deformation in elastoplastic deformation stage due to strain hardening are considered, thereby establishing a single-loading model of the joint interface. …”

Mechanical Characteristics of Hardened Concrete with Different Mineral Admixtures: A Review by Tehmina Ayub, Sadaqat Ullah Khan, Fareed Ahmed Memon

“…., porosity and pore size distribution) as well as increasing the mechanical characteristics such as drying shrinkage and creep, compressive strength, tensile strength, flexural strength, and modulus of elasticity; however, no single document is available in which review and comparison of the influence of the addition of these mineral admixtures on the mechanical characteristics of the hardened pozzolanic concretes are presented. In this paper, based on the reported results in the literature, mechanical characteristics of hardened concrete partially containing mineral admixtures including fly ash (FA), silica fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA) are discussed and it is concluded that the content and particle size of mineral admixture are the parameters which significantly influence the mechanical properties of concrete. …”
